A KNITTED SWEATER OF CORRESPONDING GARMENT ARTICLE, AND A METHOD OF MANUFACTURING IT

Abstract: A sweater or similar knitwear product is disclosed, mainly consisting of a knitwear fabric of the yarn used for the so-called cowboy or denim cloth, viz. the very wear resistant, indigo dyed cotton yarn. Such a sweater will be softer than the denim cloth, but it is desirable that both a collar and the button-bands, i.e. the front side portions holding the closing system, be made of a more rigid material. Advantageously, this material may consist of the woven denim cloth. The knitted fabric will shrink considerably in the wash, and it is complicated to stitch-on the woven fabric so as to avoid future wrinkling. According to the invention the knitwear parts for the products are knitted as fully fashioned pieces with pronounced loose knitting, and these pieces are subjected to a washing and drying treatment, whereby they shrink to a desired size and density, and only thereafter the woven fabric pieces are attached by stitching. This stitching may now be effected fully conventionally, as the said wrinkling will automatically be avoided.

Description: A KNITTED SWEATER OF CORRESPONDING GARMENT ARTICLE, AND A METHOD OF MANUFACTURING IT. The present invention relates to a knitted sweater or a corresponding garment article, and to a method of manufacturing such a knitwear article. A special feature of this article is that it is knitted of a special yarn, viz. preferably indigo dyed cotton yarn, that is the same type of yarn as used in the so-called cowboy or denim cloth, known for being extraordinarily wear resistant, though not particularly soft. The yarn is rather difficult to use in knitting machines, but it may be used, after all, and the product is a knitwear which is softer that the woven fabric and thus well suited for knitted sweaters and the like, which will then similarly be highly wear resistant. Certain parts of the garment, viz. the collar and the so-called button-bands, i.e. the vertical front side parts in which there is mounted cooperating snap fas¬ teners or provided buttons and button holes, respective¬ ly, may advantageously, both stylewise and functionally, be made of the said woven and more rigid denim/jeans fabric. The invention relates to this particular combi¬ nation, i.e. to a knitwear article having a collar of a rigid character and optionally having button-bands well suited as a mounting base for closure means, all with a harmonic fabric selection with consistent use of extra wear resistant and almost unlimited washable materials. However, there is a problem in that the knitted fabric will shrink in wash more that the woven fabric, whereby there is a pronounced risk of a forthcoming formation of folds along the woven fabric pieces. It is known that with this type of problems improvements can be made in arranging for the more rigid parts to be stretched by the stitching together with the other parts, just as during the stitching work it is possible to compress the less rigid fabric, but such a technique is unsuitable when, as here, relatively marked differen¬ ces are in question. With the invention it is a basic condition that an already indigo dyed cotton yarn is made into fully- fashioned knitwear pieces in a flat knitting machinery, and that these pieces are subsequently sewn together for forming the desired knitwear articles. According to the present invention the fully-fashioned knitwear pieces as produced by the flat knitting are made a relatively loose knitting with a pronounced oversize amounting to some 20-40% and preferably 30-35%, whereafter these pieces are subjected to a washing treatment with a fol¬ lowing accelerated drying, preferably by washing in bundles with a subsequent tumbler drying, whereafter the fabric pieces are sewn together, partly with each other and partly with one or more of the said woven fabric parts for the formation of the final product. By this method the knitwear pieces will shrink to suitable sizes and to a suitable rigidity of the knitting, and it is a resulting consequence that the woven fabric pieces can now be stitched on with a minimum of attention and with¬ out any special stretching requirements. The knitted fabric pieces will be practically ready-shrunk and 'con¬ densed', such that later on the woven pieces will not get wrinkled. In departing from a pronounced loose knit¬ ting the fabric pieces may be so widely deformed that a possible rest shrinkage later on will correspond to a modest shrinking of the woven fabric, and the conditions may be so adapted that the two types of fabric will be¬ have uniformly. As products, knitwear articles according to the invention are characteristic in that as fresh from the factory products they appear with sewn together, fully- fashioned knitwear pieces assuming a state in which, as a result of a previous washing treatment, they are con¬ densed so as to have a low residual shrinkability also in the areas where the said woven fabric pieces are sewn on, whereby the joining areas can be smooth. In the following the invention is described in more detail with reference to the drawing, which shows a sweater according to the invention. The sweater shown is generally made of a knitted fabric 2 of indigo dyed cotton yarn, with stitched-on collar 4 and button-bands band 8 as woven fabric pieces of a corresponding yarn, whereby the collar constitutes a smooth and rigid part while the button bands form solid base parts for the fixation of buttons or snap fasteners, optionally for the provision of button holes. The single knitwear pieces stitched together for forming the sweater are knitted on flat knitting machin¬ ery as fully-fashioned pieces with a relatively loose knitting and with an oversize of 30-35%. Thereafter the pieces have been brought to a laundry, where they have been washed, not necessarily with soap, and dried in a drying tumbler, whereby they have shrunk to the desired size and density. Thereafter the pieces are sewn toget¬ her, mutually and with the woven pieces 4 and 6,8, whereafter the product is handled as a unit. The woven pieces can be fixed by ordinary smooth sewing, without special complications or precautions. The new sweater may shrink slightly when being washed, but not with any disproportion between the shrinking of the knitted fabric and the woven parts, such that the sweater will generally maintain its shape. It will be understood that the invention is not limited to the bands 6,8, if any, being short or long, i.e. wether or not they are through-going along the front side of the sweater. Moreover, it may be an inter¬ esting possibility that the article may be provided with additional pieces of the woven fabric in selected areas, e.g. in a facing area at the front side, though this will be a matter of design only. The invention makes it possible to work almost uncritically with the discussed fabric combination, this applying generally to cotton products and widely comparable products.

Claims: C L A I M S : 1. A knitted sweater or a corresponding knitwear garment product, characterized in that it is chiefly made of knitted fabric of cotton yarn, preferably of the indigo dyed type, consisting of sewn-together fully fashioned knitwear pieces with one or more additional pieces of woven fabric stitched thereto, e.g. a collar or so-called buttton-bands, preferably made of a corre¬ sponding type of yarn, said knitwear pieces in the pro¬ duct of manufacture assuming a condition, in which, as a result of a prewashing and drying treatment, they are condensed so as to exhibit a low residual shrinking ability, if any, also in the areas where the woven fa¬ bric pieces are attached at smooth joints. 2. A garment product according to claim 1, charac¬ terized in that one or more woven fabric pieces are attached so as to cover one or more partial areas of one or more of the knitwear pieces. 3. A method of manufacturing a garment product according to claim 1, characterized in that the knitwear fabric is knitted of a cotton or cottonlike yarn, pre¬ ferably of the indigo dyed type, whereafter the fabric is subjected to a washing and drying treatment, and only thereafter is provided with one or more pieces of a woven fabric, e.g. a collar, preferably made of a corre¬ sponding type of yarn. 4. A method according to claim 3, characterized in that the single garment pieces for the product are knit¬ ted as full-fashioned knitwear pieces on a flat knitting machinery knitting the pieces relatively loosely, with an oversize in the length direction of 20-40%, prefer¬ ably 25-35%, while the woven fabric pieces or pieces are attached by simple sewing after said washing and drying treatment.
